One important adaptationl of; 'thislv inventionfis in, print-ing wor-,ki Where afnumber of 15. colors are. used; which require a,- nurnber ofseparate impressions to be made. upon. the paper so that; successive linpnessions`-made byditerentj plates will registen one. v vlth the other. In order to produce the desired re- 20.s nlts `it, isv necessary to4 retainthe several plates; always in a, xed relation toV each other. The device for holding theplates 1n ositionon the-base isknownfas a printers ook andthel object of thisinvent-ion isv tov 25,. provide. suchV a hook; of peculiar and novelv construction and also to provide certain novel features for-the construction of the gil baseupon which one orymoreplatesare held `ilyftrhe hooks,v all of which will beA more BQ, fully explained and the advantages andnovel'features. thereof" pointed out in oonnotin with thedescription of the embodiment. ofr the invention as illustrated inthe accompanying drawings.

' In` the construction shown in Figs. 1 to 8, inclusive,` a base is shown at 1 and printing plate 2 positioned thereon. Thet base 1 is provided with a number of slots or'channels Which, are` T' shaped and preferably extending diagonally acrosst 1e base 1. lfositioned in the-overhangi-ng side Walls of the slots or chaimels 3 are one or more racks 4, which are preferably two 1n number and con ,structed of hardened steel and arranged on.'

oppositevsides of the slots\to serve also as a bearingunder which the. hook is secured; This Will. be explained more fully herein after. The hook body inconstrueted with a.v topV or upper` portion 5' and. a bottom orl lower portion,V Iech comprising a single.

piece of materiali/tand extending theI full llength of the hoolty body and constituting upper andlower main body members, these members beingsecured together by vertically extending` portions. The jawf? is preferably formed integral with the topper-tion 5; and in angular. position thereonl Gorre-y sponding tothe angular position of channels or slots 3` in the base 1. The bottom portion 6' is cut away to receive the operating members between the vertically extending.4

portionsor ends which are joinedb'y a horizontal connecting member or portion preferably formed, integral therewith. This horizontal Connectingl member is. located between the screw operating means and the lower wall of the slotted portion when the hook. is in place therein. The locking or swing-ing members 8 are rotatively mounted in either end of the hook in the manner shown in Figs. 5, G and S, so that when the hookis-in position in a slot of the base 1 a quarter turn of the locking member. Will lock or unlock the same. The looking mem.-

bers 8 areturned by means of a sleeve 9 which also forms a bearlng for the samefand which 1s provided with a collar l() at the opposite or upper end thereof. The uppen endof this sleeve is provided With a square ysocket 11 into which the handle 12 is inserted and-by means ofy which the lockingmember is turned. This handle may be of the-angular form. show-n at 12 in Figs. 3 and 4, orlnay: beofthestraight form, asshoW-n.

at lQinFig; 7. A! pin 13 in the bottom portion. 6 ofthe hookA is positioned so as t0 enter a Slott 14:5 in y the sleeve 9 vand provides a stop for limiting the rotary movement of the rlockingrnember 8 to the necessary quarter turn for locking and unlocking. A bevel gear operates a worm or screw operating member 16 Iboth of which are rotatively mounted in the bottom portion 6 of the hook, as shown in Figs. 5 and 6. The bevel gear 15 is provided with a square socket into which the handle 12 or 12 may be inserted lfor rotating the same. The rotation of the bevel gear 15 rotates the worm 16 which engages the racks 4 in the base lvand by this means the hook is adjusted to hold the printing plate 2 in position upon the base 1. In addition to the means provided for adjusting the hook in position as just described, the

i same is also provided with the locking membersv8, which are turned by the handle 12 andcaused to engage beneath the racks 4, thus locking or holding thehook in position in the slot, as shown in Fig. 3. The locating and arrangement of the racks 4 upon the opposite sides of the slots, provides for the locking members 8 to engagebeneath these racks and as the same are preferably const-ructed of hard steel a very secure fastening means is thus provided which is not destroyed by the ordinary wear so as to render the same useless for this purpose. The teeth of the companion racks are preferably arranged on the inner edges or adjacent faces of the racks and the underside portions of the racks are preferably flat so as to be engaged by the locking means which hold the hook linplace in the slot. Ihus it will be observed that the racks constitute overhanging portions having teeth at their adjacent faces and flat surfaces at their lower sides.

In the modifications shown in Figs. 9 to 1l, the base 21 is provided with slots 23 similar to the slots in the base 1. The racks 24 are similarly positioned in these slots but the teeth of the racks are cut away at their ylower side so that the locking members 28 j of the hook engage beneath the body portion of the rack and not against the teeth, thus providing a more substantial locking means of greater durability. The top portion 25 andthe bottom port-ion 26 of the hook are' fastened together and the jaw 27 is formed integrall with the top portion 25. The locking members 28 are each provided with a sleeve 29 and collar 30 and are mounted for rotative movement by means of asquare socket 31 in the sleeve 29. The pin 33 mounted in the bottom portion26 engages in the slot 34 in the sleeve 29 to limit the rotative movement of the'loeking member 28 to a quarter turn for its locked or unlocked positions. The bevel gear is mounted for rotative movement in the bottom portion 26 of the hook and is so constructed as to be inclosed on either side thereof in the hook so that the same is protected against injury or imam from becoming gummed up from the ac'- cumulations. in the slot; The bevel gear 35 operates the worm gear 36, which is mounted for rotative movement in the bottom portion 26 of the hook so as to engage the teethof the racks 24 when the hook is placed in position in one of the slots in the base 21. This I latter construction shown in Figs. 9'to 11 provides a .compact hook construction in which the bevel operating gear is inclosed and protected and also provides a smaller. gear for line adjustment.

As many changes could be made in the above construction and many apparently widelyl different embodiments of 'my invention designed without de artin all matter contained in the above description from the'. v scope o f the appended claims, I intend that or shown in the accompanying drawings shall be interpreted as illustrative merely of an operative embodiment. of my invention and not in a limiting sense. 4
